in juce_writeJPEGImageToStream()
if (quality < 0.0f)
quality = 6.0f;
jpeg_set_quality (&jpegCompStruct, jlimit (0, 100, roundFloatToInt (quality * 100.0f)), TRUE);
should be
if (quality < 0.0f)
quality = 0.6f; // <-- here
jpeg_set_quality (&jpegCompStruct, jlimit (0, 100, roundFloatToInt (quality * 100.0f)), TRUE);
isn’t it ?
yep, but better put quality = 0.85 by default at least… a quality less than 80 produce a lot of artifacts in jpeg images…

ok, sounds sensible. Thanks chaps.
By the way, sort of related, in the same method, it would be really nice to be able to set the DPI resolution of the JPEG. I did this by adding:
jpegCompStruct.write_JFIF_header = 1;
jpegCompStruct.JFIF_major_version = 1;
jpegCompStruct.JFIF_minor_version = 2;
jpegCompStruct.density_unit = 1;
jpegCompStruct.X_density = 300; //These could be a variable
jpegCompStruct.Y_density = 300; //...
somewhere after the call to:
